DRIVING MECHANISM FOR PUMPS.

Application filed May 24, 1913.

To all whom t may concern Be it known that I, PETER C. Ionns, a citizenof the United States, residing at Chanute, in the county of Neosho andState of Kansas, have invented certain new and useful Improvements inDriving Mechanism for Pumps, of which the following is a speciiication.

This invention relates to new and useful improvements in oil wellpumping mechanism and pertains more specially to operating devicestherefor.

It is the primary object of this invention to provide novel meanswhereby the various pumps of a well farm may be operated from a centralstation.

A further object of the invention contemplates the provision of positivepowerful mechanism so constructed that a plurality of surface rodsleading from a plurality of pumps may be adjustably secured to the powerand the pumps and thereby actuated as will be hereinafter fullydescribed.

A still further object of the invention resides in the provision ofnovel means wherein suflicient pull or motion is given to the pumping orsurface rods through the medium of an eccentric or cam, the cam forminga part of the power mechanism comprising the central statio-n.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the following specification and then more particularlypointed out in the appended claim forming a part of this application.

In describing the invention in detail, reference will be had to theaccompanying drawings, wherein like characters denote like orcorresponding parts throughout the several views and in which;

Figure 1 is a side elevation of the mechanism comprising my invention;Fig. 2 is a top plan view.

In the operation of oil pumps in oil fields, in order to economize powerand fuel and reduce the operating expenses, it is usual to provide acentral station equipped with suitable power such as a gas or steamengine adapted to operate a power mechanism to which the surface rods ofthe various pumps are connected so that a numberof these pumps may besimultaneously operated even though they be located a consid- Speccationof Letters Patent.

erable distance from the central operating station.

Referring now to the drawings, wherein is illustrated the preferred formof my invention, the numeral 1 designates a suitable concrete basehaving a plate 2 bolted or otherwise secured thereto as at 3, the saidplate having a central opening formed therein through which an uprightor vertically extending shaft 4. extends, the lower end of the saidshaft being seated within a recess 5, (illustrated by the dotted linesin F ig. 1) formed within the said base. Removably mounted upon theshaft 4 and rotatable therewith, I provide a pulley wheel G, the saidwheel being retained upon the upper extremity of the said shaft throughthe medium of a transversely extending key 7, the said key fittingwithin an opening formed within the said shaft. A belt S is arrangedover the pulley wheel 6, the said belt being -driven from any suitablesource of power (not shown), thereby rotating the pulley and the shaft#I upon which it is mounted.

Disposed adjacent the base 11, preferably upon each side thereof, Iprovide an upright or vertically extending spindle 8, the said spindlesand the mechanism carried thereby being the same, but one will bedescribed in detail. The spindle S has formed integrally therewith atits lower extremity, a suitable base portion 9 which is bolted as at 10to a concrete base 11, this arrangement mounting the spindle in rigidrelation with the said concrete base 11 upon and to which it is secured.A rod 12 extends vertically throughout the length of the spindle 8, theupper extremity of the said rod being exteriorly threaded as at 13 forthe reception of a nut 1&1-, the latter adapted to clamp a. suitablebracket 15 over and upon the upper extremity of the said spindle S. Thebracket y 15 is twisted as at 1G from which point it extends to asuitable bearing 17 where it is iixedly secured through the medium ofscrews or other fastening elements 1S. This arrangement of the bracket15 over and upon the spindles S effects an immovable bearing or journalfor the vertically extending shaft 4; which, with the recess 5 formedwithin the base 1 supports the said shaft in the desired upright manner.

A gear wheel 19 is mounted upon the spindle 8 where it is free to rotateaccording to the rotation of a pinion 2O keyed or otherwise secured tothe vertically eXtending shaft 4l into which it meshes. Bearing ballsengage the under face of the wheel 19, the said bearings being retainedin proper place through the medium of a keeper or ring 22 arranged uponthe top of theibase portion 9 of the spindle. An eccentrically disposedoff-set portion :23 is formed inte grallywith and upon the upper face ofthe wheel 19, the spindle S extending therethrough. A ring or band 2d isarranged over the periphery of the eccentrically disposed olf-setportion and is provided with a hook 25 over which a detachable hoolrshaped member 25 is iitted for fastening the surface rod 26 thereto, thelatter terminating in a forked or divided end 27, one of which litswithin an eye 28 formed upon the said rod 25.

rin idler 29 in the form of a dish, is arranged over the spindle 8 inspaced relation to the cam or eccentric off-set portion 23, the saididler being provided with a plurality of openings 30, into one of which,the hook shaped member is fitted when detached or remov'ed from the hook25 of the cam. The idler 29 being immovable or stationary upon thespindle 8', it will be seen that the surface rod when secured theretothrough the medium of the hook shaped member 25, above mentioned, isheld inoperative, while the said rod when secured to the cam oreccentric 23 is reciprocated by the rotation of the gear wheel 19 uponwhich the cam is arranged, the former being rotated according to therotation of the pinion 20 into which it meshes.

Having described fully the detail construction of the power mechanism,it now remains to describe the operation thereof. rlhe surface rods 26are normally secured to the idler 29 by means of the hook shaped member25 where they are held inoperative as the said idler is immovable orstationary, this arrangement of the surface rods rendering the pumps towhich the rods are connected inoperative. lVhen it is desired that therods should be reciprocated for operating the pumps, the hook shapedmember 25 is disconnected from the idler 29 and secured to the cam oreccentric 23, by means of the hook 25 carried thereby, this connectionof the rod 26 to the eccentric reciprocates the former according to therotation of the large gear wheel 19 governed by the rotation of thepinion 2O of the driven shaft 4.

It will be seen from the above, taken in connection with theaccompanying drawings that any number of surface rods may be operatedfrom the central station or pumping power comprising my invention byattaching the rods to the cams or eccentrics carried by the large gearwheels 19; that time, labor and expenditure is decreased to a materialextent by the use of mechanism constructed as herein described; and thatpumping power of the above character may be'arranged or set up at acomparatively low cost and without necessitating the employment ofskilled labor.

In reduction to practice, l have found that the form of my invention,illustrated in the drawings and r Ylierred to in the above description,as the preferred embodiment, is the most efiicient and practical; yetrealining that the conditions concurrent with the adaptation of myinvention will necessarily vary, I desire to emphasize the fact thatvarious minor changes in details of construction, proportion andarrangement of parts may be resorted to, when required, withoutacriicing any of the advantages of my invention, as defined in theappended claims.

Having thus fully described my invention, what claim as new and desireto secure by Letters iPatent is:

fr device the character described comprising standards, a vertical shaftrotatably mounted between said standards, a bracing bar having its endportions twisted and se cured Vflat upon the tops of said standards andprovided intermediate its length with a bearing through which said shaftextends, gear wheels rotatably mounted upon the lower portions of saidstandards and provided with upwardly extending disks forming cams, agear carriedby said shaft and meshing with the gears of said standards,means for rotating said shaft, disks mounted upon said standards abovesaid cams, collars rotatably mounted upon said cams, a pump shaftextending to a point adjacent one of said lirst mentioned gears andprovided with upper and lower hooks, and a rod for selectivelyconnecting the lower hook of said rod with said collar and the upperhook with the disk positioned. above the cam.

In testimony whereof I affix my signature in presence of two witnesses.

PETER C. ICKES.
